[dell-hwmon] Changed variables in psuutil scripts for both Z9100/S6100 platforms

[paavaanan]

*- What I did
Changed hwmon variables in psuutil scripts for Z9100 and S6100 platforms. Now scripts are full-hwmon compatiable.

- How I did it
Replaced dell_s6100_lpc proc reference to SMF/hwmon1

- How to verify it
Execute the script and expect for same results. Without any issues.

- IMPORTANT NOTE
Please do merge this change along with this "sonic-net/sonic-platform-modules-dell#26" pull request. This is the real code to introduce hwmon for dell platforms. Both should be in the build to avoid breakage.

do we need to have the submodule update included in this pull request as well?

[jleveque]

@stcheng: Yes, the submodule pointer needs to be updated here before the merge.

@paavaanan: Guohan merged sonic-net/sonic-platform-modules-dell#26 earlier today. Can you please update the submodule pointer here now?

[paavaanan]

jileveque, raised a new handle here.
#1328

[jleveque]

@paavaanan: For the future, you could have pushed the submodule update commit to this branch, and it would become part of this PR. That way, all of these changes get merged along with the submodule pointer update in one atomic commit.

[stcheng]

yes. agree with @jleveque could you close the #1328 and move the submodule update into this pull request? then we won't have a broken commit in the master that would have a broken state.

[paavaanan]

@jleveque I missed the same branch part while raising the pull request. Thanks for pointing this. I raised the submodule request now.
